Weird question; what benefits could arise due to the return of a deity? I can imagine some of the good, and bad, things that might occur if the Emperor woke back up, regenerated, but let's skip Him on the Golden Throne. I've been around these forums for a long time, in my own mind, anyway, and every so often, someone throws up a "save Isha" thread, or something. Now, obviously I am considering something similar, or I wouldn't bother everyone with my prattling, but what benefit would there be, once one cleared the monstrous hurdle of "HOW would you save Isha? HOW would you weaken Slaanesh enough, directly, to break Asuryan, Vaul, Korunous, or the others out of her...hmm... let's go with 'gullet'?"
Say you DID manage to free one, or more, of the Edlar deities. I'm going to admit, right here, I've never fully even understood what type of beings they were, be they Old Ones, psychic constructs of the Eldar, just particularly old, and powerful Eldar, who have been deified, or what, but if one DID come back, I'm not sure they'd be able to DO much of anything, short of momentarily raise the Eldar people's morale. None of them seemed powerful enough to face Slaanesh, as a newborn, and I'm betting She Who Thirsts has only grown in strength, since. Isha wasn't strong enough to escape Nurgle, either, and no amount of time has persuaded the Eldar to bring back the fragments of Khaine, and have him reunite as a singular individual; even Cegorach, who has survived all this time, hasn't been able to do much.
I get that the Ruinous Powers are strong, and saving any Eldar deity would be tough, but could any of them actually DO anything for the Eldar people, were they to be freed? Right now, the fluff in the story of mine doesn't even know if what they are talking to really is Isha, or if it is merely a daemon. If it IS the real deal, is she still Isha, or has 10,000 years as Nurgle's prisoner, and taste-tester, ruined her forever? Is she now allied with the Plaguefather, and is this all a trap to do something horrible to the rest of the Eldar, from an angle they didn't even see coming (it's NOT Slaanesh!) This bit doesn't matter, yet, but, as I've babbled repeatedly, I'm not sure how the return of the Eldar gods could benefit their dwindling race, even if it was possible. Any ideas? For Isha, I thought she MIGHT increase birth rates of the fading Space Elves, but I'm not sure that would REALLY be an advantage. If it was somehow another one, I really don't know what they'd give/do.
Thanks for getting through it, and for any ideas you toss up. Have a good one!
